20 Precision Viscosities · 50–1000 cSt

Silicone Performance Fluid

Rhodex's bestselling silicone shock oil range. Twenty exact viscosities from 50 cSt ultra-light tuning oil to 1000 cSt heavy damping. Pure 100% silicone, heat-stable, seal-safe, and perfectly blendable for custom setups.

Why It's #1 on Amazon

Damping Consistency, Bottle After Bottle

Generic shock oils suffer from viscosity variance — your 400 cSt today might behave like 380 cSt next month. That kills setup repeatability. Professional racers can't tune what they can't trust.

Rhodex Silicone Performance Fluid is engineered to exact cSt specifications, batch after batch. Pure silicone base — no PAO, no mineral oil dilution, no thickener compromises. The result: damping you can trust, race after race.

That's why thousands of racers chose Rhodex as their go-to shock oil. And it's why you'll find it at the top of Amazon's RC silicone oil bestseller list.
